White Spots on Your Teeth — What Are They, and What Can Be Done?

20 Jun

Have you noticed chalky, pale patches on your teeth that don’t seem to shift no matter how well you brush? You’re not alone — and the good news is that these marks are treatable.

🔬 What Are White Spot Lesions?

White spot lesions (WSLs) are areas of early enamel demineralization. When acid from bacterial plaque dissolves the mineral structure of enamel, it creates microscopic pores beneath the surface. These pores scatter light differently from healthy enamel, giving the characteristic opaque, chalky appearance.

Common causes include:

∙ Poor oral hygiene and plaque accumulation

∙ Orthodontic treatment — brackets make cleaning harder and increase demineralization risk

∙ Fluorosis (excessive fluoride intake during tooth development)

∙ Dietary habits high in fermentable carbohydrates

∙ Genetic and developmental factors

💊 Why Do They Matter?

WSLs are not just a cosmetic concern — they represent the earliest visible stage of the dental decay process. Left unaddressed, active lesions can progress to cavities requiring more invasive treatment.

✅ How Are They Treated?

The approach depends on the severity and cause of the lesion. Evidence-based options include:

∙ Fluoride varnish — the gold standard for remineralisation; strengthens enamel and can arrest early lesions over time

∙ CPP-ACP products (such as GC Tooth Mousse) — milk-derived calcium and phosphate complexes that support enamel repair

∙ Resin infiltration (ICON) — a minimally invasive technique that fills the porous enamel with resin, restoring optical properties and improving aesthetics immediately

∙ Microabrasion — controlled removal of the outermost enamel layer, effective for superficial discolouration

∙ Combined therapies — current research suggests combining approaches, such as resin infiltration with fluoride varnish, produces superior outcomes compared to single treatments alone
